BCI PO Box 470 Depew, NY 14043 1-800-865-2950 Concrete Safeguard W Technical Information
Designed to form a hydrophobic barrier beneath the surface and seal out moisture while remaining highly vapor permeable. ¨ Premium Water-Based Siloxane/Silane Impregnating Sealing Compound for Masonry.
PRODUCT DESCRIPTION Concrete Safeguard W is a siloxane/silane water based high performance penetrative masonry water repellant. Concrete Safeguard W is a VOC Compliant emulsion that deeply penetrates into new (14 day minimum) or existing concrete and masonry surfaces. Surfaces treated with Concrete Safeguard W have a totally natural appearance. Concrete Safeguard W will chemically bond with the substrate. The visual appearance of the treated surfaces will show normal or no change resulting from product application. Concrete Safeguard W penetrates into the pores and capillaries of the cement reacting with the moisture and chemicals in the substrate, polymerizing and sealing the pores, which prevents water, chemical, and chloride ion penetration. It will not darken the surface nor impair the natural breathing characteristics of the treated surface.
USE INSTRUCTIONS Apply only to untreated surfaces. Concrete Safeguard W may be applied over itself. A test application my be necessary to ensure compatibility and desired water repellency. Test areas are also beneficial to determine application rate and procedures. If the material in the test area does not fully penetrate due to coatings or an inadequately cleaned surface, use a concrete cleaner, degreaser or an acid etch. Low pressure spray application, with proper nozzle, provides the best results. However, product may be applied with brushes or rollers. DO NOT THIN OR DILUTE. DO NOT APPLY TO SURFACES BELOW 40 ° OR ABOVE 110 °.
ADVANTAGES · Alkaline stable-suitable for new "green" concrete. · Penetrates deeply to produce long lasting protection on vertical or horizontal surfaces. · Reduces corrosion of rebar and surface erosion in reinforced concrete. · An effective salt or chloride screen. · Does not alter natural surface texture or appearance.. · Superior water repellency for porous surfaces including concrete, fibrous cement, natural stone and brick. · Prolongs the surface life and prevents damage from within by maintaining vapor permeability of concrete. · Protects brick, concrete, and masonry.

APPLICATIONS Approximate rates for sealing broom finish, rough textured is 125-175 square feet per gallon. Approximate rates for sealing slick trowel finish is 250-350 square feet per gallon.
General Although the recommended spread rates are generally adequate, there may be variations in substrate porosity, which may require more or less material for optimum results. With Concrete Safeguard W, one coat is normally adequate. However, two coats reduce the potential for inadequate coverage. Always apply with a uniform pattern until surface is saturated and the material starts to run down or puddle. When applying, it is suggested that the substrate receive an initial light mist coat to break the surface tension. Then should be followed by a uniform flood coat which allows just enough material to carry a 4 inch rundown from contact point and a uniform coating on the surface. Surface residues, pools, and puddles should be brushed out until they completely penetrate the surface.
Maintenance Remove all dirt and debris by sweeping.
PRECAUTIONS · Store this product in a sealed container. · Apply over 40° and below 110°. · Protect from freezing. · 6 month shelf life. Although Concrete Safeguard W is an extremely effective water repellent with long lasting service life, it is not designed to exclude water penetration under the following conditions: · Open structural cracks · Hydrostatic Pressure · Visible holes in substrate · Wind-driven rain that exceeds 20 MPH. Porous surfaces with cavities throughout can be treated with BCI TOP SEAL after the Concrete Safeguard W Application.
